I got a PD35 nearly a decade ago. I loved it. I only got a few years out of it before it went on the fritz, but I blame myself, as I was super rough with it, basically abused it.
I then purchased an Olight M2T Warrior. Found it super heavy compared to Fenix, so didn't carry it much (and by super heavy I mean an ounce more). Otherwise it's a great light. I repurposed it to being a bike light, and it has done four or five years of that for me now, and still going strong, though I have had some finicky tail switch function lately. It used to be I could partial press the tail switch to toggle turbo, and the light would extinguish when I released. Now I have to press harder and by the time the light is on, it has clicked on, and I have to click it again to turn it off. Not a big deal. I typically used the side button for it anyway.
What I carry for EDC is a Klarus XT2 C at home. I've had this one for six years. The thumb switch started going on the fritz three years ago, right around the end of the warranty. It stopped working altogether and I bought a new one, slightly upgraded model. That one is what I carry when I leave the house, but I still carry the fritzy one at home, because after the new one arrived, I gave it one more try before I would toss it out, and when I tightened the rear cap the light flickered on for a split second. I thought no way it's dead if it will do that, so I thought to try stretching out the battery contact coil a bit. It worked. The light functions, but not properly. I can partial press and hold the tail switch (the only switch on the light) to toggle turbo consistently, which is fine and all I really need it to do. But if I try to click it on, which used to work just fine, it will click and activate in turbo, then immediately when I release my thumb and hear the second click, it turns off... sometimes. Other times not. So I just make a point to keep that as my at home EDC light, and have trained myself to only rely on it as a partial hold and toggle light. The newer one that I carry away from home still does everything it's supposed to.
I have also been thinking of a new light lately, to replace Fritzy. It's not an emergency yet.
